CAD
Explain the advantages of being technologically literate.
Because it means understanding technology and being comfortable with it.
Name two words that describe a person that works in technology.
The tow words are technician and technologist.
Drawing that shows the circuits and components of electrical and electronic systems.
Schematic Drawing
Identify the workers who do technology.
Technicians and technologists.
Identify Isaac Newton.
Isaac Newton was a famous British scientist who investigated he motion of the planets.
Replica of a proposed product that looks real but does not work.
Identify seven technology resources.
People, Information, Tools and Machines, Capital, Time, Materials, and Energy
Explain why people need skills and imagination to create new technology.
to create new products; to build them
A statement that clearly defines a problem to be solved.
Problem Statement
An open-loop system includes input, process, and output but no way of controlling the product. A closed-loop system adds feedback.
Explain why people diagram plans.
To help explain and clarify plans.
A state in which all parts of a design work together.
Unity
Identify common engineering materials.
These include wood, plastics, metals, ceramics, and composites.
Explain why a dull tool is more dangerous than a sharp tool.
A dull tool requires more force to operate, making it more likely to slip.
The design of equipment and environments to promote human safety, health, and well being; also called ergonomics.
Human Factors Engineering
Explain natural materials.
Organic materials, such as wood, leather, and cotton, come from living things. Inorganic materials, such as stone, metals, and ceramics, come from mineral deposits.
Identify the architects goal when designing a structure.
A state of steadiness or stability; one of the principles of design.
Balance
List the six steps in problem solving.
Define the problem, collect information, develop solutions, select one, put it to work, and evaluate it.
Identify the influence engineering has on design.
They ensure a product works well, is durable, reliable, and easy to maintain.
A material made by mixing a metal with other metals or materials.
Alloy
Explain what a problem statement includes.
A problem statement identifies the problem and includes criteria and constraints.
Tell the difference between a hypothesis and a scientific law.
A hypothesis has not been tested. Scientific Laws have been tested through experimentation again and again.
A restriction on a product.
Constraints
Describe the alphabet of lines and scale drawing.
Lines vary depending on their purpose, and drafting has rules about how to draw each type of line. A scale drawing shows an object's actual shape drawn smaller or larger than the actual size.
Define optimization.
Optimization is making the most of positive features while reducing negative features.
Something that supplies help or aid to a system; can be a source of information, capital, supply or support.
Resource
Identify the purpose of models and prototypes.
A model shows how something will look; a prototype is a working model of a proposed project.
Explain the difference between a thermoplastic and a thermosetting plastic.
Thermoplastic products can be melted, formed, and recycled. Thermosetting plastics can be heated and formed only once.
